Abstract

Experiments were conducted to observe the influence of variable light intensities on the mycelial growth of Pleurotus ostreatus on both solid and liquid media. Light intensity of 100, 200 and 300 lux along with complete light and darkness were evaluated. 200 lux supported the best mycelial growth i.e., 8.26 cm and 10.11 g/ml respectively in solid and liquid media followed by 100 lux (8.17cm and 6.92 g/ml) and complete darkness (7.94 cm and 6.29g/ml). After 200 lux the growth was observed to decline. The minimum mycelial growth was recorded on complete light with 6.87 cm of mycelial diameter in solid medium and 4.08 g/ml of mycelial mat in liquid medium. Results signify that P. ostreatus prefer diffused light for its growth instead of complete darkness and full light conditions.
